GROUP MANAGER I NEED HELP | 2 GROUPS TO 1 PLAYER

So I have group manager and have all of the groups running and working. I have a prison server and want to figure out how to add 2 groups to one person. So for example I want to have it like: [A] SpeedyGames [Elite] Elite is the donator rank and A is the rank they are currently on. I also want it so when they go to the next rank, the donator rank will follow them and stay there. If someone knows how to help me PLEASE do so! Thanks!

~SpeedyGames
Keep in mind that the donator ranks are: Donator, Silver, Gold, Thug, Gangster, Elite
[Here is What My Group Manager Ranks Are and How They Are Setup]

# Group inheritance
#
# Any inherited groups prefixed with a g: are global groups
# and are inherited from the GlobalGroups.yml.
#
# Groups without the g: prefix are groups local to this world
# and are defined in the this groups.yml file.
#
# Local group inheritances define your promotion tree when using 'manpromote/mandemote'
